WATER-WASTE CONTROL.

Specification of Letters Patent.

Patented May 20, 1919.

Application filed April 11, 1918. Serial No. 227,898.

To all whom it may concern:

Be it known that I, ARTHUR C. CooswnLL, a citizen of the United States,residing at Detroit, in the county of Wayne and State of Michigan, haveinvented a new and useful Improvement in Water-\Vaste Controls, of whichthe following is a specification.

This invention relates to a waste preventing device for use with bibs,faucets, and all kinds of cocks. It is especially designed so that itcan be used in bibs already in use by simply threading the inside of theportion that screws into the supply pipe.

In a number of cities metered water service is now in use and in a greatmany of the cities large industrial plants pay for their water by meter.Consequently it is of importance that the water be not wasted bycareless workmen. Most of these bibs are now provided with a quickopening valve by reason of a thread of considerable pitch. Consequentlyit is usual for the workman to throw the faucet completely open insecuring a drink or washing and there is a great waste incurred thereby,which amounts to a great many dollars in a year in a large manufacturingplant. The device also avoids objectionable splashing which oftenfollows when the bib is turned on full.

To obviate this I have designed a device for adjustably regulating theflow in such bibs regardless of how far open the valve is thrown.

In the drawings,

Figure 1 is an elevation of a bib fitted with my.regulatory plug and asection of the end of the supply pipe.

Fig. 2 is a side elevation of the plug itself.

Fig. 3 is an end elevation of the plug itself.

Fig. 4 is a longitudinal section of the end of the bib that screws intothe supply pipe.

The bib or faucet is shown in Fig. 1 with the regulating plug a screwedinto the threads of the nipple b by which the bib is attached to theinternally thread'ed end of the supply pipe f. This regulating plug isdetailed in Fig. 2 and it will be seen that 1t has one or more orifices0 cut through the threads of the plug and giving a communication fromthe exterior to the interior of the plug. The end view shown in Fig. 3shows that the plug has a closed end with a screw-driver slot 03 bywhich the plug may be turned in and out of the threads of the nipple.The other end of the plug is open.

When the bib itself is made to take a plug of this kind it is preferableto employ a shoulder e to prevent the plug being turned in further thanis necessary to bring the last portions of the orifices into operation.In fact in threading the interior of the nipple this shoulder may befirst madeby reaming the interior of the nipple .out slightly even in abib that has already been in use.

It will now be apparent that by putting these plugs in the ends of thenipples of the bibs, an exact regulation of the amount of water thatwill fiow through the bibs when the ordinary valve is completely opened,can be secured. By just turning the plug into the nipple a few turns allthe orifices in the sides of the plug allow the water to flow throughand the amount will be dependent upon the combined area of the orifices.A nice adjustment can be secured by screwing the plug in and partiallycovering the ori fices so as to get the precise restricted area desired.Fig. 1 shows one position of adjustment.

From this description it will be obvious that a very much reduced flowof water is secured in the bib so as to eliminate waste in places wherewaste is expensive.

What I claim is:

In a water waste control, the combination of a bib and supply pipe, oneof which is provided with an internally and externally threaded nippleand the other with an internally threaded socket to receive the nipple,and a hollow exteriorly threaded and side perforated plug screwedpartially into the nipple and closed at its end which projects out ofthe nipple and open at its opposite end, the end of the nipplecooperating with the perforations in the plug when the plug is screwedinto or out of the nipple to varyingly regulate the water flow t0 thebib.

In witness whereof I have hereunto set my hand on the 8th day of April,1918.

ARTHUR C. GOGSWELL.
